| Abstract: | A sort of P/M RE-Fe-Ni-Cr used in cylinder liner of cement concrete pump is developed, A coating consisting of RE-Fe-Ni-Cr is formed on the cylinder liner surface of cement concrete pump by plasma spraying. The effects of microstructure and content of rare earth elements on wear resistance of Fe-Ni-RE alloy is studied, the result shows that the higher density and uniform microstructure can be obtained in the material by adding rare elements, and the material possesses high hardness and good wear resistance. |
